stopping threads without using local var?

[kam hagh]

hi, here's my code,

#include <iostream>
#include <unistd.h>
#include <thread>

using namespace std;

void Blink();

bool blinkit;
int main()
{
	blinkit = true;
	thread blink(Blink);
	sleep(5);
	blinkit = false;

	blink.join();
	return 0;
}

void Blink()
{
 	cout << "Hellow ";
	while(blinkit){
		cout << "0_0";
		cout << flush;
		sleep(1);
		cout << "\b\b\b";
		cout << "^_0";
		cout << flush;
		usleep(500000);
		cout << "\b\b\b";
	}
	cout << "\n Bye !" << endl;
}

the problem is i don't want to use local vars , is ther anyway do end the loop safely(removing all the vars used in function and ect) without using a local var ?

Check out std::condition_variable:

that's gonna help me a lot for other apps, thanks :) i love this forum :)

but is ther anyway to do it without a local variable? (only by creating a var inside the main or Blink function ! that is removed after the thread ends ! )

the links you gave me still require me to use local variables !

Your current code does not use a local variable. Do you mean "global" instead?

You could always pass the variable by reference to the thread.
